Only one of my two horns seems to be working, all I get is a wimpy high pitched peep. For a while the other one would come on occasionally but now I think it's dead. I would like to test the wiring for voltage down at the horn before I go and buy a new one. I was told that I would need to remove the front bumper to get at the horns. I have searched for info on how to take the bumper off but have found nothing. Can anyone help please?
Thanks
Ian
